% of Population without Health Insurance, by Zip Code (ZCTA5) — Miami Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

Uninsured rates in the Miami metro vary dramatically by zip code, ranging from near 0% in parts of Key Biscayne and western exurban areas to upwards of 35–50% in select zip codes near Hialeah and pockets north of Coral Springs. A pronounced corridor of elevated uninsurance (20–30%+) runs through central Miami-Dade, encompassing Hialeah, parts of Miami proper, and surrounding working-class neighborhoods, while coastal Broward County zip codes around Fort Lauderdale and Hollywood generally fall in the 10–20% range. The lowest rates cluster along the western Everglades fringe and in affluent coastal enclaves, underscoring a clear socioeconomic gradient from inland urban cores to peripheral and beachfront communities.
